Silent Agony

The meaning of Atheism differ depending on the Atheist though for me Atheism isn't about rejecting the existence of a big sky daddy because you can't reject the existence of something that doesn't exist in the first place, it's kinda like santa clause whence the majority of children may believe such fairy tale but once they grow up and realized such entity don't really exist they would just say "oh, ok." And carry on like it didn't happen. That's what it is.
